Answer:
V = 2143.57 cm^3
Step-by-step explanation:
We want to find the volume of the sphere
V = 4/3 pi r^3 where r is the radius and pi = 3.14
V = 4/3 ( 3.14) ( 8)^3
V = 2143.57333 cm^3
Rounding to the nearest hundredth
V = 2143.57 cm^3
The number of people which gets 1/6 of the pizza as required for lunch the next day is; 4 persons.
<h3>What is the number of people who get 1/6 of the pizza for lunch?</h3>

On this note, the 4/6 fraction of pizza left mean: 4 × 1/6.
Therefore, only four persons get lunch.

Answer:
Distribution 4, mean is 20 and standard deviation is 3.2
Step-by-step explanation:
The standard deviation tells us on average how far each of our data values is from the mean. A standard deviation that is larger than the others will mean a distribution that is more spread out than the others; 3.2 is the largest standard deviation, so Distribution 4 has the greatest spread.
